Problems solved by technology

[0003] However, if a part of the metal core is not provided and a conductive member is provided on the inner peripheral side of the core metal, if capacitive coupling occurs between the external electrode and the conductive member, parasitic capacitance will be generated in the external electrode.

Embodiment Construction

[0015] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0016] figure 1 and figure 2 A steering wheel 10 as a steering body according to the present embodiment is shown. The steering wheel 10 is provided in a steering device as a steering device of a vehicle, and is disposed on the vehicle front side of a seat (driver's seat) where a passenger (driver) who drives the vehicle sits. figure 1 The schematic structure of the steering wheel 10 is shown in a front view, figure 2 The main part of the steering wheel 10 is shown in a sectional view cut along the radial direction of the steering wheel 10 . In addition, in the drawings, the radial direction of the steering wheel 10 is indicated by an arrow R, and the circumferential direction of the steering wheel 10 is indicated by an arrow L. As shown in FIG. In addition, in the drawings, the vehicle front side is indicated by an arrow FR, the right side in the vehicle...

Abstract

In the present invention, a steering wheel (10) includes a rim part (12) in which a shield layer (42) is disposed between a sensor electrode (36) and a rim core bar (18). The shield layer (42) is disposed extending along the sensor electrode (36). Due to this configuration, the occurrence of capacitive coupling between the sensor electrode (36) and the rim core bar (18) can be appropriately suppressed by the shield layer (42), and parasitic capacitance generated at the sensor electrode (36) can be reduced.

Description

technical field [0001] The present invention relates to steering bodies. Background technique [0002] In the steering wheel sensor disclosed in Japanese Patent Application Laid-Open No. 06-27494, external electrodes are provided on the outer peripheral side of the core metal of the ring portion, and the capacitance between the core metal and the external electrodes is detected. [0003] However, if a part of the metal core is not provided and a conductive member is provided on the inner peripheral side of the metal core, if capacitive coupling occurs between the external electrode and the conductive member, parasitic capacitance will be generated in the external electrode. Contents of the invention [0004] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a steering body capable of reducing parasitic capacitance generated in sensor electrodes. [0005] A steering body according to a first aspect ...
